| 摘 要： | 根据对象的输入输出采样数据，用数值计算方法分析热工对象模型的阶次。对于用曲线拟合方法建立热工对象的数学模型，本算法可以为模型阶次的确定提供依据。仿真例子表明，算法对无零点对象的分析结果是准确的。

| Abstract: | Based on the sampled date of the system input and output,the paper presents a method for numerically analysing the system model order.The algorithm developped is helpful in providing the ground of argument for defining the model order for the modelling the controlled object by means of curve fitting.Examples in simulation show that the new method gives quite accurate result for the non-zero object. |
